New Gizmo To Measure Dry Eye- Do We Need It?

A new software for the Oculus Keratograph provides quantitative analysis of distortions in the placido rings and can thus give data on tear breakup time. I suppose it may be helpful to demonstrate this to patients who remain puzzled as to why they are tearing and have dry eye at the same time. Since it’s just a software upgrade, it may be worth it- I can’t imagine buying expensive hardware to prove dry eye.
